Add support for URI remapping (#620)
Remaps allow mapping from a URI pattern to a different URI.

The syntax is

```
lychee --remap 'https://example.com http://127.0.0.1'
```

Some use-cases are
- Testing URIs prior to production deployment
- Testing URIs behind a proxy

Be careful when using this feature because checking every link against a
large set of regular expressions has a performance impact. Also there are no
constraints on the URI mapping, so the rules might contradict with each
other.
Remap rules get applied in order of definition to every input URI.

Add support for excluding paths from link checking (#623)
This change deprecates `--exclude-file` as it was ambiguous.
Instead, `--exclude-path` was introduced to support excluding paths
to files and directories that should not be checked.
Furthermore, `.lycheeignore` is now the only way
to exclude URL patterns.

Extend reqwest client settings (#617)
This sets a HTTP connect timeout (for stability)
and a TCP keepalive (for performance).

The connect timeout should help with flaky servers, which
would block the runtime and therefore other requests.

The keepalive helps when making many requests to the same
host. This is a very common pattern for checking internal documentation,
which is an important use-case of lychee.

The settings are currently not configurable by the user
and set to sane defaults. We might make this configurable in the future
if there is demand to do so.

Extract more status information from reqwest (#577)
Recently we cleaned up the commandline output to trim away redundant
information like the URL, which occured twice.
Unfortunately we also removed helpful information from reqwest, which
could support the user in troubleshooting unexpected errors.

This commit reverts that.
We now extract the meaningful information from reqwest, without being
too verbose. For that we have to depend on the string output for the
reqwest error, but it's better than hiding that information from the user.
It is fragile as it depends on the reqwest internals, but in the worst case
we simply return the full error text in case our parsing won't work.

Regression: Ignore invalid URLs (#571)
With the refactoring the URL checking as a workaround for the upstream
reqwest panic on invalid URLs, we introduced a regression, which caused
unsupported URL schemes to show up as errors in the lychee output.

This commit changes the behavior such that invalid schemes get ignored
again by making a differentiation between truly invalid URIs which would make
reqwest panic, and ones which are valid but just not handled by reqwest.
The check was moved to `check_website` such that the invalid URIs would
not be checked three times in a loop before erroring out.

Allow input URLs without scheme (fixes #567)
This requires `Input::new` to return a `Result`, because the URL
parsing could fail when prepending `http://`.

We use http instead of https, because curl does as well:
70ac27604a/lib/urlapi.c (L1104-L1124)
Missing files will be interpreted as URLs from the command line
and these can be invalid, but that's not seen as an error anymore.

Optimize plaintext extractor for small strings (#565)
Immediately return for very small strings which cannot be valid URIs.

The shortest valid URI without a scheme might be g.cn (Google China)
At least I am not aware of a shorter one. We set this as a lower threshold
for parsing URIs from plaintext to avoid false-positives and as a slight
performance optimization, which could add up for big files.
This threshold might be adjusted in the future.

Improved IPv6 filtering support (#501)
This commit uses crate `ip_network` to determine whether an IPv6 address is
link-local or unique local.

Note that this extra dependencies can be removed once rust-lang/rust#27709 is
stabilized.

Replace plain String with SecretString for GitHub token (#509)
This commit changed the type of `lychee-lib::ClientBuilder::github_token` from
`String` to `secrecy::SecretString` to fortify the secret management within our
program.

Note that this won't affect TOML configuration of `lychee-bin` because
`serde::Deserialize` is still implemented for `SecretString`.

Use captured identifiers in format strings (#507)
Makes for arguably cleaner-looking code.
The downside is that the MSRV is 1.58
https://blog.rust-lang.org/2022/01/13/Rust-1.58.0.html

Given that nobody uses lychee as a library yet
and we have precompiled binaries, it's an acceptable
tradeoff.

replace hubcaps by octocrab (#502)
This commit replaced `hubcaps` by `octocrab`, which has more downloads per month
and receives more frequent release updates.

The caveats are:

1. When instantiating the API client, `octocrab` doesn't offer you a way to
specify custom user-agent. But I would argue that, at least presently, this
doesn't seem to cause issues.
2. `octocrab` doesn't export as much details of its error types as `hubcaps`
does. So we will have fewer control on the display of the error message. But I
would also argue that this is not really important. Though we should do more
tests to make sure the error looks good enough.

* hide implementation details in error message

lychee-lib::client reworked (#500)
This commit mainly added or improved documentation for `lychee-lib::client`
module.

But it also contains a few API changes:

- `ClientBuilder::client()` now consumes itself instead of taking a reference.
  This helps to avoid a few unnecessary clones.
- `ClientBuilder::build_filter()` was a private function and is inlined to avoid
  unnecessary clones.
- Added a new crate-scoped function `Uri::set_scheme()`.

* added notes on deprecated site-local network

Add html5gum as alternative link extractor (#480)
html5gum is a HTML parser that offers lower-level control over which tokens actually get created and are tracked. As such, the extractor doesn't allocate anything tokens it doesn't care about. On some benchmarks it provides a substantial performance boost. The old parser, html5ever is still available by setting the `LYCHEE_USE_HTML5EVER=1` env var.

Add caching functionality (v2) (#443)
A while ago, caching was removed due to some issues (see #349).
This is a new implementation with the following improvements:

 * Architecture: The new implementation is decoupled from the collector, which was a major issue in the last version.    Now the collector has a single responsibility: collecting links. This also avoids race-conditions when running multiple collect_links instances, which probably was an issue before.
* Performance: Uses DashMap under the hood, which was noticeably faster than Mutex<HashMap> in my tests.
* Simplicity: The cache format is a CSV file with two columns: URI and status. I decided to create a new struct called CacheStatus for serialization, because trying to serialize the error kinds in Status turned out to be a bit of a nightmare and at this point I don't think it's worth the pain (and probably isn't idiomatic either).

This is an optional feature. Caching only gets used if the `--cache` flag is set.

8d445a3a4b Be more permissive around private GH repos
The Github API doesn't handle checking individual files inside repos or
paths like `github.com/org/repo/issues`, so we are more
permissive and only check for repo existence. This is the
only way to get a basic check for private repos. Public repos are not affected and should work
with a normal check.

Use tokenizer for extraction; add benchmark (#424)
This avoids creating a DOM tree for link extraction and instead uses a `TokenSink` for on-the-fly extraction. In hyperfine benchmarks it was about 10-25% faster than the master.

Old: 4.557 s ± 0.404 s
New: 3.832 s ± 0.131 s

The performance fluctuates a little less as well.

Some missing element/attribute pairs were also added, which contain links according to the HTML spec. These occur very rarely, but it's good to parse them for completeness' sake.

Furthermore tried to clean up a lot of papercuts around our types. We now differentiate between a `RawUri` (stringy-types) and a Uri, which is a properly parsed `URI` type.
The extractor now only deals with extracting `RawUri`s while the collector creates the request objects.

Improve concurrency with streams (#330)
* Move to from vec to streams

Previously we collected all inputs in one vector
before checking the links, which is not ideal.
Especially when reading many inputs (e.g. by using a glob pattern),
this could cause issues like running out of file handles.

By moving to streams we avoid that scenario. This is also the first
step towards improving performance for many inputs.

To stay as close to the pre-stream behaviour, we want to stop processing
as soon as an Err value appears in the stream. This is easiest when the
stream is consumed in the main thread.
Previously, the stream was consumed in a tokio task and the main thread
waited for responses.
Now, a tokio task waits for responses (and displays them/registers
response stats) and the main thread sends links to the ClientPool.
To ensure that the main thread waits for all responses to have arrived
before finishing the ProgressBar and printing the stats, it waits for
the show_results_task to finish.


* Return collected links as Stream
* Initialize ProgressBar without length because we can't know the amount of links without blocking
* Handle stream results in main thread, not in task
* Add basic directory support using jwalk
* Add test for HTTP protocol file type (http://)
* Remove deadpool (once again): Replaced with `futures::StreamExt::for_each_concurrent`.
* Refactor main; fix tests
* Move commands into separate submodule
* Simplify input handling
* Simplify collector
* Remove unnecessary unwrap
* Simplify main
* cleanup check
* clean up dump command
* Handle requests in parallel 
* Fix formatting and lints
